Description
Model M133 master unit is one phase electric power/energy calibrator. It can supply unit under test with one phase accurate AC voltage and current with calibrated phase shift or DC voltage and current. Output voltage can be set in five ranges up to 280 V and output current in six ranges up to 30 A. Simulated electric power can be set independently in each phase. Frequency can be set in range from 15 Hz to 1 kHz with resolution 0.001 Hz to 0.01 Hz. Calibrator is equipped with 5 1/2 digital DC meter with DC ranges 20 mA or 10 V for direct calibrating of various types of power transducers.
M133 calibrator offers two types of defined distortion of main sinusoidal output signal. The first distortion is based on adding defined amount of harmonic or interharmonic spectral components up to 5 kHz. The second type of distortion is based on amplitude modulation of output sinusoidal signal by sin or squarewave modulation signal in frequency range from 0.001 Hz to 50 Hz. Maximum depth of modulation is 30 %.
Three-phase electric power/energy calibration system can be optionally built-up using one M133 master unit and two M133f slave units. The slave units contain power stages of each additional phase output. They are fully controlled from master unit via rear panel special interface. Maximum output voltage between two voltage phases is 560 VAC. Current outputs can be joined together offering total range to 90 A AC/DC
